I'm getting WA on codeforces, while its working correctly for that case on my system. Also the checkers comment is too weird.

Can't find file K:\invoker-prod\work\codeforces6\25bd73a20640963248bd7f3788f1424e\check-1b3eb285945d2168cb2ee5ad536c2f21\run\output.txt [invokerId=7b1ec022e70f30d35dabadbce49e1a1e, location=203279216] (1).
